For my computer it works:

$ cat /etc/udev/rules.d/99-hide-disks.rules
KERNEL=="sda1", ENV{UDISKS_PRESENTATION_HIDE}:="1"
KERNEL=="sda3", ENV{UDISKS_PRESENTATION_HIDE}:="1"
KERNEL=="sda4", ENV{UDISKS_PRESENTATION_HIDE}:="1"
# and so on for other disks.

Maybe it would be smart to add it to the FAQ?
